Abstract
A thermally conductive sheet includes a sheet body and an adhesive layer. The sheet body is obtained by curing a thermally conductive resin composition. The thermally conductive resin composition includes a polymer matrix component and a fibrous thermally conductive filler. The adhesive layer is formed on at least one surface of the sheet body and imparts tackiness to the at least one surface of the sheet body. A volume of the adhesive layer is 0.0002 cm3 or more and 0.001 cm3 or less per 1 cm2 of the sheet body.
Claims16
A thermally conductive sheet comprising:
- a sheet body obtained by curing a thermally conductive resin composition comprising a polymer matrix and a fibrous thermally conductive filler dispersed in the polymer matrix;
- and
- an adhesive layer formed on at least one surface of the sheet body and imparting tackiness to the at least one surface of the sheet body,
- wherein a volume of the adhesive layer is 0.0002 cm3 or more and 0.001 cm3 or less per 1 cm2 of the sheet body.
A method for producing a thermally conductive sheet, comprising:
- molding a thermally conductive resin composition comprising a polymer matrix and a fibrous thermally conductive filler dispersed in the polymer matrix into a predetermined shape;
- curing the molded thermally conductive resin composition to form a thermally conductive molded body;
- slicing the thermally conductive molded body into a sheet to form a molded body sheet;
- and
- forming an adhesive layer on at least one surface of the molded body sheet, the adhesive layer imparting tackiness to the at least one surface of the molded body sheet,
- wherein a volume of the adhesive layer is 0.0002 cm3 or more and 0.001 cm3 or less per 1 cm2 of a sheet body of the molded body sheet.
